A power outage caused a combined sewage and stormwater overflow in the city of Bremerton sewage system Sunday, according to a notice from Kitsap Public Health District. About 4,600 gallons were spilled.

The no-contact advisory will remain in effect through Friday. Signs have been posted at public access points advising people to stay out of the water. Shellfish harvests are already closed in the area due to ongoing pollution.
